To all whom z'tmay concern Beit known that I, l aizpna'ron C. Soon",

a British subject, residing at Detroit, in the county of lVayne' and State of'Michigan,

have invented a new and useful Hose;

Clamp, of which the following is a specifi .tova hose without liability of the clamp opening or untwisting entirely.

A further object of the invention is to.

reduce the cost of hose clamps of this character by enabling the same to be v constructed of light material, withoutfim'pair- 'ing their strength or causing them to buckle or crimp at-the point Where the pressure is applied for drawing'the terminals of the strip inwardly.

, With these and other objects in view the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the-accompanying drawing, and pointed out in the claims hereby appended, it being understood that various changes in the form, proportion, size'and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. p v

In the drawing: Figure 1 is a perspective view of a hoseclamp constructed in accordance with this invention. Fig. 2 is a sectional view of the same. Fig. 3 is a perspecstrip.

tive view-of-the metallic strip rolled toform a hose clamp and illustrating the means for limiting the opening or uncoiling of the Fig. 4 is a plan view of the blank from whichthe strip is formed.

Like numerals of reference designate corresponding 'parts'in all the figures of the drawmga v In the accompanying drawing, 111 which is illustrated the preferred embodiment of the lIU'GIIt-lOIl, l designates a strip of sheet metal or other suitable material provided at a point intermediate of its ends at one.

Specification of Letters Iatent. Paten-tgd Apn 1'3;

twisting or turning to enable the strip to be partiallycoiled to present a continuous sur-g face to a hose or other flexible tube and t o 7 side of the center with a'n enlargement 2 it i having a longitudinal slot 3- 015a width to permit the strip to passthrough it without; a

permit the terminal portions to be drawn together around the hose engaging portion The terminal; portions ll of the blank are laterally enlarged and'ta'pered, I .forming substantially diamondshaped .portions which are shaped bystamping or of the strip.

pressing to provide terminal ears 5 andwebs orflanges 6 arranged. at opposite s des ofthe strip and connecting the ears 5 with theside portions of the strip In the formation of the ears and fianges,.the approximately diamond shaped terminal portions are bent on-the dotted lines a, 6 shown in Fig. 4 of the drawing. The ears and flanges or webs of one end of the strip are adapted to pass,

through the slot 3j'and the terininalsof the.

strip areadjustably connected by'means of a bolt 7 provided at one end with a head S and threaded at the othIer-end to, receive a nut 9. The ears are provided with openings 10 for the passage of the bolt, and one of the ears is engaged by the head 8 of the bolt I and the other end 9, which fits between the .side flanges or webs of such end, and'is thereby held against rotary movement when the bolt is turned to draw the ends of the strip together for applying the desired pressureto the hose or other tube. .In order to facilitate applying the clamp to a hose, the strip is provided adjacent to one of its ends with laterally projecting lugs 11 formed integral with the strip and adapted to be bent up at right angles to the said strip to enable them to pass through the slot 3, and after the said lugs have been passed through the slot, they are then bent outwardly into the plane of the ad acent portion of the strip,

and as they form a laterally enlarged portion of greater width than the slot 3, it will be apparent that the will prevent the adjacent terminal. portion 'fioni being drawn backwardly througlnthe slot. The laterally projecting lugs 11, which have straight inner transverse edges 12, preferably extend v to the side edges of the slotted enlargement Q. lVhen it .is desired to apply the clamp to .a hose. the bolt may be removed and the resilient-strip will bend out to approximately the position shown 1]] F 1g. 3 of thedrawing and will be limited in such opening moy .10 between the ears when the nut is at the outer sired pressure. The strip is also provided ment, so that there will be no danger of the strip entirely uncoiling. After the coiled strip has been placed afoundthe hose, the

ends of the strip may be drawntoward each' other and connected by the bolt, which will enable the hose to be clamped with the de- 'with an'imperforate enlargement- 13, projecting at the side edges of the strip and being of length to extend across the space "endjof the bolt and the clamp is adjusted to if its greatest diameter. This enlargement 13,

which lies beneath the bolt and'stiflens the clamp between the' connected terminals of the strip, will enable the terminals to be drawn together by the bolt to apply the de- "13 sired s ure to the hose without liability of causing the-strip to buckle or bend beneath the bolt. This will maintain an even:-

pressure upon the hose and by widening the I strip at this point, the clamp may be constructed of much lighter material "-than otherwise, This will lessen the cost .of

manufacture without affecting the strength of, the de'vioef What is claimed is':' I

1. A clamp of the class described consisting of a, single strip of metal provided with alongitudinal slot of a size topermit one end of the strip to passv through it without twisting, the end of the strip which is passed through the slot being provided with a latv a longitudinal slot of a size to permit one 4 I end of the strip to .pass through it without twisting, the endof the strip which is passed 7 through the slot'being provided with; a pair of laterally projecting lugs adapted to be bent inwardly so asto pass through the slot,

said lugs, when bent outwardly,- forn1ing stops for limiting the opening novenient of the clamp, and means for adj ustably connecting the terminals of the strip. 7 y

Intestimony thatl claim the foregoing as myv own, I have hereto affixed-my signature in the presence of two-witnesses.
